I have a custom VPC which has 6 public subnets in 6 AZs.
When I tried to create Aurora Serverless, I do see my VPC in the VPC dropdown but there is only 1 item 'Create new DB subnet group'.
I'm expecting my VPC has available subnet groups already.
I have researched a lot already, even compare another VPC (which is working) with my VPC, I don't see anything differences from VPC to Subnet to RouteTable to Security Group ...
Please advice.
You need to bundle the subnets you want to use on your instance on a db subnet group
, you can't add the subnets directly.
It is very easy, as seeing here.
